CULTIVATOR.

Application filed. October 9, 1925. Serial No..61,545.

This invention comprehends the provision of a motor operated cultivator or the like, designed to be used with any of the standard cultivating tools, and to accomplish the desired work more accurately7 and With a minimum of time and effort. f

The nature andadvantages of the invention will be better understoodwhen the following detailed description is read in connection with the accompanying drawings, the invention residing in the construction, combination V`and arrangement of parts as claimed..

.In thevdrawings forming part of .this application, like numerals of reference indicate similar parts in the several views, and where- Figure 1 is a side elevation of the machine constructed in accordance with the present invention.

.Figure is adetail view of the means employed for adjusting the auxiliary frame and showing one position of parts.

Figure 7 is a similar view showing another position of the parts. j

. Figure 8 is a fragmentary view partly in section showing the manner of bracing and supporting the frame Yof the machine from the front axle thereof.

Referring to thedrawings in detail, A indicates generally the running gear ,of a motor operated vehicle, and wherein 10 represents vthe frame thereof. A motor of the Ford type is employed and indicated at 12, and this motor consequently. includes a planetary transmission indicated at 13'. Are rangeddirectly behind this transmission and operatively connected with the drive Ishaft of the machine is a sliding transmission 14 including the control lever 15, which is `employed for the reduction of' speed as the occasion may require. At the front end of the machine the frame 10 is braced by members 16 arranged in .divergent relation and adjacent the transverse end member of the main frame, as illustrated; The members 16 are connected with a bolt' 17 passed through the front axle 18 of the machine, and when it is desired to hold the body of the machine from movement with relation to the axle I employ side braces 19 adapted to be secured to the opposed sidesof the 4frame 10, and designed to straddle and repose upon the front axle 18.4 The rear end of the frame 10 is braced by a transverse memberl 21 upon which' the frame 10'reposes, the member 21 being connected with the spring perches 22 in place of the vusual transverse spring, and arched as at 23- to pass over the dilferential..

Carried by and suspended from the main frame ofthe machine is an auxiliary lframe clearly shown in igures 1 and 2, and which auxiliary frame is rectangular in plan and of a size to project an appreciable distance beyond both sides of the machine, as shown. This auxiliary fra-me includes a front bar 24 arranged in advance of the front wheels of the machine and transversely thereof, and which bar is braced and supported by diagonally spaced bracing membersy 25 which have their corresponding rear extremities suitably secured to the sides of the main frame, while their forward extremities are secured to the front bar 24 at the ends there- `corresponding forward extremities are pivotally connected with the front bar 24. These vmembers are also pivotally connected with the bar 27 as are also the spaced parallel members 28 of the frame, which have their forward extremities pivotally connected with the front bar 24. Again, the front bar 24 of the frame is braced and supported by spaced members 29 which are of angular contour to be secured to the sides of the main frame 10 from which they project forwardly and at an inclination to the front bar 24 with which they are secured. This construction and arrangement of parts not only supports the auxiliary frame upon the main frame of the machine, but allows the auxiliary frame to be raised or lowered with relation to the ground to properly Vposition the vcultivator tools for the work to be accomplished, and also allows the auxiliary frame to be tilted endwise when the machine is moving` over inclined or hilly territory.

The rear bar 27 includes spaced upper and lower sections, as clearly shown in vfigure l, and between these sections are passed bolts 30 which are utilized to hold the cooperating parts 31 and 32, respectively, of a clamp associated with said bar, these clamps being used in conjunction with the shanks 33 of the cultivator tools indicated at 34. The shank 33 of each tool is provided with slots 34 so that the said tools are susceptible of vertical adjustment withrelation to the adjacent bar 27 of the auxiliary frame, and also susceptible of tilting adjustment by reason of the slot and pin connection, indicated at 35. In addition to these adjustments of the cultivating tools the lattermay be `also slid y. along the bar 27 so as to space the tools any desired distance apart, and to accomplish this it isy only necessary to loosen the bolts 30 to slide theV latter between the sections of the transverse bar 27, as will be readily understood.

For the purpose of adjusting the auxiliary frame, I employ a shaft 36 journaled transversely of the frame 10 and having crank arms 37 and 38 at the ends thereof. The crank arm 37 is pivotally connected with the adjacent end of a link 39, while the lower end of this link is pivotally connected with a link 40 associated with the adjacent archshaped bracing' member 26, as clearly shown in Figure 3. The other crank arm `38 is also vconnected with the adjacent arch-shaped bracing member 26, but indirectly so through a construction of means to be presently described, which allows the frame in its entirety to be raised and lowered with relation to the ground incident to the operation of the lever 41, and independently operated by means of a lever 42. when it is ldesired to 'only raise one end of the frame. This connecting means includes a frame 43 which is pivotally connected as at 44 with the crank arm 38. Pivotally mounted on this frame 43, as at 45, is the lever 42 above referred to, the lever 41 being carried by the shaft 36. A link 46 is pivotally connected with the lever 42 adjacent its lower end, and provides a connection between this lever andthe ad- Vreason of this construction and arrangement of the rod 50 that the connecting means between the crank arm 38 and the auxiliary frame is afforded the proper `rigidity to maintain the parts in working relationinci- 4dent to the operation ofeither of the levers 41 and 42, respectively. `When it is desired to raise and lower the auxiliary frame in its entirety from the front bar 24, the lever 41 is utilized, and .when this lever is operated the frame 43 and its associated parts all move as a ,unit under the' influence of the lever 41. However, when it is desired to raiseor lower one end of the auxiliary frame independently of the other end thereof, the lever 42 is employed, which allows the frame 43 to be swungupon its pivotal connection 44 to so adjust the auxiliary frame independently of the lever 41, as will be readily kunderstood The levers 41 and 42 are arranged within convenient reach of the operator and can be very easily manipulated for the purposes intended. Y

While itis believed that from the. foregoing description the nature and advantages ofthe invention will bereadily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described, and that such changes may be resorted to when `desired as fall within the scope of what is claimed.

I-Iaving thus described the invention, what is claimed as new, is
